                  Comprehensive summary is presented of work published on the sorption of gases in silicate and ionic crystals.  The relative accessibilities of the interstitial adsorption sites increase in the order:  beryl< silicate glasses<silica glass<harmotome<levynite< mordenite<gmelinite, chabazite, and a synthetic crystalline zeolite BaAlSi₂O₆.2-3 H₂O.  Special attention is given to a summary for analcite and for the last 6 of the zeolites listed above—of their sieve action in adsorption, their thermodynamics of adsorption, and their kinetics of adsorption.
